to get initialised before other driver start using it.

drive-type is not supported for pinctrl-tegra20 and pinctrl-tegra30
so set drvtype_reg to -1 for them.

NVIDIA's Tegra114 added two more configuration parameter in pinmux i.e.
rcv-sel and drive type.
rcv-sel: Select between High and Normal VIL/VIH receivers.
RCVR_SEL=1: High VIL/VIH
RCVR_SEL=0: Normal VIL/VIH
drv_type: Ouptput drive type:
33-50 ohm driver: 0x1
66-100ohm driver: 0x0
Add support of these parameters to be configure from DTS file.
Tegra20 and Tegra30 does not support this configuration and hence initialize their
pinmux structure with reg = -1.
Originally written by Pritesh Raithatha.
Changes by ldewangan:
- remove drvtype_width as it is always 2.
- Better describe the change.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Rather than having a single tegra-pinctrl driver that determines whether
it's running on Tegra20 or Tegra30, instead have separate drivers for
each that call into utility functions to implement the majority of the
driver. This change is based on review feedback of the SPEAr pinctrl
driver, which had originally copied to Tegra driver structure.
This requires that the two drivers have unique names. Update a couple
spots in arch/arm/mach-tegra for the name change.

This adds a driver for the Tegra pinmux, and required parameterization
data for Tegra20 and Tegra30.
The driver is initially added with driver name and device tree compatible
value that won't cause this driver to be used. A later change will switch
the pinctrl driver to use the correct values, switch the old pinmux
driver to be disabled, and update all code that uses the old pinmux APIs
to use the new pinctrl APIs.
